Self-consistent noise characterization of quantum devices
Won Kyu Calvin Sun, Paola Cappellaro
Characterizing and understanding the environment affecting quantum systems is critical to elucidate its physical properties and engineer better quantum devices. We develop an appro…
Improved entanglement detection with subspace witnesses
Won Kyu Calvin Sun, Alexandre Cooper, Paola Cappellaro
Entanglement, while being critical in many quantum applications, is difficult to characterize experimentally. While entanglement witnesses based on the fidelity to the target entan…
Environment-assisted quantum-enhanced sensing with electronic spins in diamond
Alexandre Cooper, Won Kyu Calvin Sun, Jean-Christophe Jaskula +1
The performance of solid-state quantum sensors based on electronic spin defects is often limited by the presence of environmental spin impurities that cause decoherence. A promisin…
Identification and control of electron-nuclear spin defects in diamond
Alexandre Cooper, Won Kyu Calvin Sun, Jean-Christophe Jaskula +1
We experimentally demonstrate an approach to scale up quantum devices by harnessing spin defects in the environment of a quantum probe. We follow this approach to identify, locate,…
